Rational using of soil cover in Baraba lowland plain with dominative development of hydromorphic and saline soils must be take of knowledges on its spatial structure. Soil cover of Baraba is very important for agricultural activity in Novosibirsk Region, so it was studied so well during 20th century. Now we have significant data on properties, regimes, genesis for main types of soils ans soil complexes in Baraba lowland plain. Influence of ecological factors on the spatial organization of Baraba soil cover is not open in detail, especially in lowland relief forms such as drains and river beds. The part middle-scale map under investigation is on the south periphery of North-Baraba between 55º27′N and 55º37′N and 75º13′E – 78º30′E and correspones 200 km from W to E and 20 km from N to S. Such size gives to see the main particularities in spatial structure of Baraba soil cover and is enouth to determine the influence of climate on sublongitudine trends in quantitative states of soil cover components in Baraba forest steppe. Analysis of digital soil map using GIS means is the most resultative way for quantitative comparison in soil cover structure. Correction of soil contour limits is available now by aerophoto registration on unmanned flying machines. Hydromorphic soils (including subhydromorphic) dominate in soil cover structure of selected fragment of digital soil map for northern forest steppe in Baraba lowland plain where they have 90–98% of a square. Automorphic soils have a little contours on well grenaged upper parts of landscape. The most common there are solonetzes meadows, peats low moor gleic soils, meadow-chernozemic solonetzic soils, meadow alluvial, chernozemic-meadows solonetzic soils. The studies are the basis for the creation of adaptive-landscape-land information systems. Automation of agricultural production management processes will significantly reduce the risks arising from the adverse agro-climatic conditions in the territory of the Novosibirsk region, and the low agricultural value of soils.
